How You Benefit

Cost savings and comfort

The Earthlinked System is the one system that can deliver 100% of all heating and cooling needs, with no additional pumps or equipment required. That means warm and toasty in the winter and cool and comfortable in the summer. The simplicity of the units allows for more efficient transfer of heat, essentially delivering the most powerful geothermal HVAC system available with the added benefit of FREE hot water.

Free hot water

It's not often that you can purchase one system that handles a wide range of home needs. A well designed EarthLinked geothermal system can heat domestic water and keep a pool warm in addition to providing comfort within the home. This range and versatility makes the technology a multi-purpose solution that can benefit any homeowner while making life easier for people and planet.

Quiet and reliable

Since the EarthLinked System is fully enclosed and protected from the elements, it requires less maintenance. The simpler design has less components to fail, no water pump and no extra heat exchanger. This not only boosts the lifespan of the technology, but also decreases maintenance costs associated with owning a home.

Tax credits

You can take advantage of up to a 30% federal tax credit, as well as other local and state incentives, rebates and financing by installing an EarthLinked geothermal system in your home. Learn more.

Increased property value

Green building practices such as geothermal solutions have been gaining increasing attention for their ability to offer energy savings and lower utility bills. As more people recognize these potential rewards, they are beginning to seek out homes that offer sustainable systems such as geothermal heating and cooling. Recent guidelines have provided real estate appraisers with a specific method for documenting energy efficient upgrades, allowing realtors to better analyze the differences between the values of green homes and traditional properties.

Decreased carbon footprint

Because the EarthLinked System uses the solar energy stored within the earth to heat and cool your home, you can reduce your need for natural gas or oil and other forms of finite fuel resources. This helps you decrease the carbon footprint associated with your home and saves thousands of pounds of greenhouse gas emissions each year. The U.S. EPA and DOE have determined that ground source heat pumps have the lowest environmental impact of all heating systems, and they reduce consumption and corresponding emissions up to 75%.

Why Solar?

IT'S A CHOICE WITH MANY BENEFITS

Homeowners across the globe are seeing the
solar light. The reasons vary for each person, though they mainly come down to the
following

IT'S FREE

Solar-energy systems allow you to capture free sunlight and convert
it into usable power in your home.

IT'S CLEAN

Solar energy can be used to heat and cool your home, but it has almost no impact
on the global climate. By comparison, electricity generated by power plants produces
carbon dioxide emissions that scientists say pose serious threats to the
environment.

IT'S INFINITELY RENEWABLE

While nonrenewable energy sources like oil, gas and coal are becoming increasingly
scarce, the sun's energy is limitless. Wherever sunlight shines, electricity can be
generated.

IT CAN REDUCE YOUR UTILITY COSTS

Having a system that creates solar energy
means you use less electricity from your utility company, and that can contribute to
lower heating and cooling costs. This is significant, especially when you consider
56% of energy use in a typical U.S. home comes from heating and cooling*. To find out
how much you can save by harnessing energy from the sun, use our solar calculator.

IT COMES WITH INCENTIVES

The U.S. federal government and some states provide
tax credits for renewable-energy systems. Depending
on where you live, you may also be eligible for incentives through your utility
company. To find out what incentives are available in your area, visit dsireusa.org.

IT INCREASES YOUR ENERGY SELF-RELIANCE

The more sunlight harnessed by the
system, the less electricity you need from your utility supplier.

IT CAN ALSO INCREASE YOUR HOME'S VALUE

An investment in a solar-energy system
may improve the value of your home. Surveys conducted by the U.S. Department of
Housing and Urban Development have shown that, for every $1000 saved per year,
$20,000 may be added to a home's value.

IT'S EXTREMELY RELIABLE

The sun has been around for billions of years and is
likely to burn on for billions more to come. And when you consider how a trusted name
like Lennox is putting it to economical use in the home, it's easy to see solar
energy's future is bright.*U.S. Department of Energy statistics

How Solar Works

LEARN HOW TO PUT THE SUN'S POWER TO WORK IN YOUR HOME.

Solar-energy is an
infinitely renewable resource that uses the sun's rays to generate electricity for
use in your home. By going solar, you can reduce your energy costs and also lower
your dependence on fossil fuels, thereby making your own contribution to a cleaner
environment.

THE BASICS

A residential solar-energy system uses solar modules, made up of
photovoltaic (PV) cells, to harvest the sun's energy and convert it into electricity
that can be used to power your lights, appliances and other electrical devices in the
home.

TYPES OF SOLAR SYSTEMS

Grid-tied PV systems

A grid-tied system is the most common and least expensive of all residential solar
systems. It allows you to use your own solar-generated electricity to save energy and
reduce costs. At times when the PV system isn't producing electricity, such as at
night, electricity is provided by the utility company's grid, or network of power
stations.

One of the benefits of a grid-tied system is that any excess electricity produced
by your solar system can be fed back to the grid through a process known as
net-metering. With net-metering, which is available in most areas, when you use
electricity from the grid your meter spins forward. The less electricity you use from
off the grid, the slower your meter spins. Even better, when you are feeding
electricity back to the grid, your meter spins backwards!

It's important to note that the government and utility company rebate
incentives that can make installing a solar system so much more affordable usually
aren't available unless your system is grid-tied.

Stand-alone PV systems

Stand-alone PV systems, also called off-the-grid or off-grid, operate
independently from the utility grid, providing all of the electricity needed in the
home. Stand-alone systems are much more expensive than grid-tied systems. However,
for homes located in remote areas without utility service, or where installing power
lines would be extremely costly, a stand-alone system is a good option.

ADVANTAGES OF THE SUNSOURCE® HOME ENERGY SYSTEM

The SunSource Home
Energy System is a grid-tied PV system that uses as its platform a high-efficiency
air conditioner or heat pump from the Dave Lennox Signature®
Collection. These units come solar-ready, which means you can add solar modules to
create a solar energy system, if and when you want one.

Upgrading to a high-efficiency air conditioner or heat pump from Lennox will allow
you to reduce the energy demand of your home before adding solar.

You can start small, with one or two modules, and add more (up to 15 total, per
outdoor unit) when your needs change or budget permits.

When the heat pump or air conditioner isn't running, the solar power can also
operate other electrical devices in your home.

With net-metering, any surplus power goes back to the grid possibly entitling
homeowners like you to a credit.

A communication module, which send performance information for each solar
module to a monitoring website, allows you to see the system status, energy
production, and also shows the environmental benefits of using renewable energy for
your home.

Steps to Solar

A SIMPLE GUIDE FOR GETTING STARTED WITH SOLAR.

Are you ready to get started
on the path to real energy savings? The following steps will help you prepare for
installation of a SunSource® Home Energy System.

Step 1 - CALL YOUR LOCAL LENNOX DEALER FOR A CONSULTATION.

Your Dealer has a detailed planning checklist to help determine
whether your home meets all the requirements for installation of a SunSource Home
Energy System.

Step 2 - SEE IF YOUR ROOF GETS ENOUGH SUN.

A southern exposure is best, and your roof should be relatively
free of shade from trees or structures such as chimneys. Your Lennox Dealer will
perform tests to estimate the site's monthly and annual solar energy generation
potential.

Step 3 - DETERMINE WHETHER YOUR ROOF IS BIG ENOUGH.

Each solar module requires about 15 square feet of rooftop surface
area. The number of modules you want installed determines how much space you need.
Your Lennox Dealer will help you with the calculations.

If you belong to a Homeowners' Association (HOA), you might be
required to submit your solar installation plans for approval ahead of
time.

Step 5 - UPGRADE YOUR INTERNET SERVICE IF NECESSARY.

An always-on Internet connection with broadband router is required
to take advantage of the SunSource system's web-based performance monitoring
service.

STEP 6 - CHECK FOR PROPER UTILITY SERVICE AND ELECTRICAL
WIRING.

Your Lennox Dealer will check the grid power supplied by your local
utility company and also inspect your home's distribution panel to make sure all
required specifications are in order. Your dealer will also need to identify all
local electrical code requirements to ensure compliance.

Step 7 - ASK YOUR LOCAL UTILITY COMPANY IF SOLAR-FRIENDLY PROGRAMS
ARE IN PLACE.

Ask whether your utility company has a net-metering program that
will allow you to receive credit for at least a portion of the electricity your
SunSource system generates. You will also want to learn whether you must meet
power-generating thresholds to qualify for valuable rebate and incentive
programs.

Lennox System Performance

HOW DOES THE SYSTEM WORK?

The SunSource® Home Energy System
reduces the amount of electricity needed from your utility provider to put you
in control of your utility bills. This energy-saving system harnesses
solar-energy and uses it first—before using electricity from the utility
company—to power your air conditioner or heat pump. The solar power
that's collected can also operate other appliances and electronics when the
heating and cooling system is not in use. What's more, if the SunSource system
generates more solar power than is needed, that power will be sent back to the
utility company, possibly entitling homeowners to a credit.

For more details on how the different system components work together to lower
your utility bills, view our solar house.

WILL THE SYSTEM WORK AT NIGHT AND ON CLOUDY DAYS?

Your system will not
work at night because the solar modules need sunlight to produce power. Solar
modules will still produce power on cloudy or overcast days, but at a reduced
level.

HOW LONG WILL THE SYSTEM LAST?

We stand behind the Lennox name and the
quality that has made us a global leader in home comfort. Because the

performance data for each module to a website, where you can view systems
status, energy production and environmental benefits online, including carbon
offsets, in real time.

DO I NEED AN INTERNET CONNECTION TO USE THE COMMUNICATION MODULE?

Yes,
an Internet connection is required to receive the full benefits of the online
monitoring system, and to view energy production, and environmental benefit
information. The monitoring service is provided free for five years.*

WILL GOING SOLAR COMPROMISE MY COMFORT IN ANY WAY?

At the heart of the
SunSource® Home Energy System is a solar-ready heat pump or air
conditioner designed to deliver the same optimal comfort and high-efficiency
performance offered by other systems from the Dave Lennox Signature®
Collection, Lennox' finest offering of heating and cooling systems.

WHAT HAPPENS IF THE POWER GOES OUT?

In the event of a power outage
caused by a storm or some other problem, the SunSource system will shut off.
Once power is restored by your utility company, the system should turn back on
automatically along with lighting, appliances and other household
electronics.

Lennox Solar Modules

ARE THE SOLAR MODULES EASILY DAMAGED?

The modules are made of tempered
glass and are laminated to a resilient substrate. They are rugged, durable, and
weather-and-impact-resistant.

WILL THE MODULES LOOK AWKWARD OR OBTRUSIVE ON MY HOME?

The hardware
that mounts the modules to your roof allows them to integrate nearly flush with
the surface for a discreet appearance that does not detract from the overall
appeal of your house.

HOW MANY MODULES DO I NEED TO PRODUCE ENOUGH ELECTRICITY TO RUN MY HOUSE?

The number of modules you need depends on several factors, including
the size of your home, angle of your roof and so on. We have a tool that can
help you determine the amount that's best suited to your requirements.

WILL I NEED A NEW ROOF BEFORE THE MODULES ARE INSTALLED?

The ideal
situation for installing solar is to have a roof that's in good condition. That
way, you won't have to bear the cost of re-installing the solar modules if your
roof needs to be replaced or repaired within a few years.

DO THE MODULES NEED TO FACE SOUTH?

Yes, South-facing modules are best
to maximize sun exposure. The closer to south the system faces, the greater the
electrical output from the solar modules.

WHAT HAPPENS IF THE SOLAR MODULES ARE SHADED?

Ideally, the solar
modules should be installed in areas where they are free from obstructions that
can cause shading, like trees and buildings. But, the unique design of the
modules could provide energy savings, despite varying climate and lighting
conditions. Unlike typical solar-panel systems, which have one inverter for the
complete array, each SunSource module has its own microinverter that converts
solar energy into usable electrical power. So any issue that might affect one
module, such as cloud cover, doesn't impact the other modules.

WHAT HAPPENS IF THE SOLAR MODULES ARE COVERED BY SNOW?

If it snows, our
solar modules are installed at the angle of the roof, which may allow the snow
to slide down and melt within a short period of time under normal
circumstances. In the event of an extreme accumulation, you may need to brush
off the snow to get solar power.

DO I NEED TO CLEAN THE SOLAR MODULES?

In most regions, rain cleans them
off automatically. However, if you live in a dusty industrial area, you may see
a performance improvement from periodically spraying the modules with water.
Please note that detergents and high-pressure hoses should never be used for
cleaning.

DO THE SOLAR MODULES NEED TO BE MOUNTED ON MY ROOF?

Modules are
typically mounted on the roof, but can also have a pole foundation. Ground
installations are best if your house is heavily shaded, or if buildings or
other obstructions limit available space on your home's roof.
